Description

Steps to reproduce:

This happens in Flex 4 and the MAX 2010 Preview Build
1. Setting the NumericStepper thus:

<s:NumericStepper id="cutPoint1NS" value="-1.5" stepSize="0.1" snapInterval="0.10" minimum="-2.0" maximum="2.0" baselineShift="0.0" allowValueWrap="false" />

2. When rendered, start clicking the up arrow.

Actual Results:

-1.4
-1.3
-1.2
-1.1
-1
-0.8999999999999999
-0.8
-0.7
-0.6000000000000001
-0.5

you get the idea.

-0.9
-0.8
-0.7
-0.6

...
again, you get the idea.

Workaround (if any):

Let me know if I've done something wrong here, but this seems very straight forward. "stepSize" is set to a value that is easy to add, I assume. Why would I be getting these odd values?
